SEWER.

SPECIFICATION forming part of Letters Patent No. 232,948, dated. October 5, 1880. Application fiieu July 23, isen. (No model.)

To all whom tt may concern:

Be it known that I, FANNY DERNHAM, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Sewer Grating` or Protector, of Which the following is a speeifi- 4 cation.

My invention has for its object the preventon, to a large extent, of the accumnlation in the server or catch'basin of bulky and pestilential debris. I employ for this purpose, at the entrance of the sewer, a series of grated screens or fenders, so formed as to arrest and retain all the inore bnlky matters that are brought to the sewer-inlet by the gutter.

In the accompanying` drawings, Figure 1 is a perspective view of a sewer-inlet provided with one of my grated protectors. Fig. 2 is a Vertical section of the same. Fig. 3 represents, by a similar section, a modification of my protector, adapted for use with that form of sewer-inlet Which has a verge or fiange projecting' downwardly and inwardly from its crown.

A represents a sewer-inlet; B, the month or Opening thereof. Adapted to lit and occupy the mouth B is a vertical grating, O, attached to and extendin from whose front is a grated fender, D, Whose bars are somewhat more widely separated than those of the grating C. ProjectingI upwardly and forwardly from the top of fender D are cui-ved claws E, for the detention of such bulky objects as branches of trees, fragments of lumber, ngs, straw. and garbage. Attached to rear of g'rating O is a perforated or finely-g'rated catch-box, F, Which is adapted to retain the major portion of such solid matters as traverse the opening's of the gratings O and I). The catch-box F may be closed on top by a grated lid or cover, G.

In Operation, my protector, as often as it becomes charged with street-\vaslii1igs, is drawn from the inlet and lifted by means of a derrick, such as city scavengers are commonly provided With, and relieved ofits contents by dumping,` the same in the scavengerls Wagon, after Which the empty protector is returned to its place in the inlet.

For those seWer-inlets which have a verge, H, a downwardly-projecting grate, I, may take the place of the grating C, and discharge the functions of the catch-box, while those of the grating` O may be discharged by a hanging grating, J, which, being` hinged at K to the grate I, occupies the entra-nee of said grate in the manner shown in Fig. 3.

A fender, It, similar to fender D, is secured in position by engagint` over hooks L, on the grate-front.

Whatever form be adopted, my protector will oonsist, essentially, of a series of grated reeeptaclesot' gradnally-inereasing fineness in direction of the drain.

My invention is designed to prevent, to a large and important extent, the aeenmulation of pestilential obstrnctions in the sewer, by providing` a means of separating the solid from the fluid portions, Which enables the scavenger to remove such solid portions before they have had time to ferment and become injurions.

In addition to the above-cited sanitary benefits, my invention is advantageons in an eco. nomical aspect as a labor-saving` device.

I am aware that it has been proposed to place in the bottoms of sewercatclrbz-tsins various forms of traps and strainers, in order to arrest and facilitate the removal of debris, and I therefore disclaim novelty in such strainers, broadly considered.

I claim as new and of my inventionz- I. The series of grated receptaoles D C F, of grad[rally-increasing' fineness, adaptetl to oc` eupy the seirer-mouth and to be easily removed therefrom substan tiall y as and for the purposes set forth.

2. In combination with the series of sewen gratings, the claws E, that project up Ward an d forward from the fender D, in the manner and for the objects designated.

In testimony of which invention I herennto set my hand.

Attest: FANNY DERNHAM.
